The Taco 3450-2 is a combination boiler feed valve and backflow preventer designed for hydronic heating systems. This unit integrates two functionalities into a single body, providing efficient operation and space-saving benefits.
This valve protects your heating system water from flowing back into the supply piping. It automatically fills closed systems to the desired pressure and allows for easy cartridge replacement without draining the system.
